      <p class="warning">
        Do not send configure and installation questions to the
        petsc-users mailing list. Always send them (and include
        configure.log and make.log) to <a href="../documentation/bugreporting.html">petsc-maint@mcs.anl.gov</a>
      </p>

      <h3>Notes:</h3>
      <ul>
        <li>petsc-announce is an announcement only list. [i.e users cannot post on this list]</li>
        <li>petsc-users and petsc-dev are subscriber-only lists. [i.e to post to this list - you have to subscribe first]</li>

        <li>
          the lists have limits on message sizes - so if you have to send in
          attachments - most likely the appropriate place is <a href="../documentation/bugreporting.html">petsc-maint@mcs.anl.gov</a>
          - not the mailing list.
        </li>

        <li>
          The mailing lists are migrated from majordomo to mailman in Jan-09.
          So links to archives, and subscription procedures have changed since
          then - as indicated above.
